Abstract

Experiments have been conducted on an adiabatic toroidal compressor with tangential injection of two 14-15-keV, 3-4-A beams of H0 or D0. The ion-temperature rise for both H+ and D+ plasmas is 70-80 eV (i.e., 35-40%), consistent with theoretical expectations for charge-exchange-limited energy transport at neutral-atom densities ≅ 109 cm-3. The injected ions are found to decelerate in agreement with classical theory and produce an initial plasma ion heating rate of ∼ 20 keV/sec.
